" IMPROVEMENT jlN MILK-cooLERs.

Specification forming part of Letters Patent No. 168, 104, dated September 28, 1875 application led March 18, 1875.

To all whom lit may concern Be it known that I, rinnovo. PALMER, nf

. Charlotte, county of Chittenden and State of Vermont, have invented ani-Improvement in Milk-Cooling Apparatus, of which the following is a specification:

This invention relates tornan @lass 0f milkcoolers wherein a number of milk-pans are set into water-tanks, and in such manner as to leave a space between'the pans and tanks for the circulation of water. v

The principal objects sought in this improvement are, first, the complete control of the quantity of water in the tanks, according'as the temperature of thesame may be, and the quantity of the milk in the pans Amay be more or less; second, the concentrating the water directly beneath the bottom of the milkpans y when desirable; third, obviating the necessity of-drawing olf the water to a point lower than the top of the milk-outlet pipe if the removal of the milk-pan is requisite.

. Figure l is atop view, showing a portion of the apparatus with the milkpan in position. Fig. 2 is a top view, `showing a portion of the apparatus with the milk-pan out. Fig. 3 is a section through the appaiatus on lines A B,

' Figs. 1 and 2, (milk-pan in position.) Fig. 4

is a back view of the apparatus. Fig. 5 is a front view ot' the apparatus. Fig. 6 is a section through water-regulator online E F, Fig. 7. Fig. 7 is a section through water-regulator on line C D, Fig. 6. Fig. 8 is an enlarged sec- 'Y H,'and plug I. (See Fig. 8.) J, J, and K are water-outlet pipes. The inside of tank A is itted with a continuous bolster, LL, and supports for theimilkpan M M.

In Figs. 6 and 7, (details of water-regulator,)

4O is the outlet from water-tank, I being the adjustable gate, properly packed, and workingvertically in guides R R, controlled in height by the screw S and wheel T, and being made water-tight by the screw-pressure bar U A and wheel F. This regulator is used to control the height of water in tankA when it rises above the bottom of the milk-pan A.

In Fig. 8, (detail of connection between milkpan and outlet to same,) G is the outlet-pipe, having its upper end formed with shoulders G1 and G2, inside andout, former to allow the vtube V on its inside to be jin line with the inside of the outlet-pipe G. Shoulder G2 is to form bearing on the bottom of the tank A, and to which it is firmly secured. The pipe G runs above bottom of pan`A for purpose of prevent'- ing water getting into it when not fully drawn ofi', and obviates the necessity of fully drawing oi the water, thereby saving both water and labor. V is a truncated tube connected tothe milk-pan A', and having around it, at a line at the bottom of the milk-pan, a packing,

H, of rubber or other suitable material, said packing forming a water-tight joint between the pipe G and the bottom of the milk-pan A', and prevents the water in the tank A passing intol the pipe Gr and mixing with the milk. I is a plug of "any suitable form and material, and having connected to it a ring, X, to which .is attached a chain or wire for drawing it out of the tube V. This tube V is truncated to facilitate the removal of the pan Al when it is necessary to cant the pan.

In Fig. 6, (water-regulator,) Z Z indicate a line at which the shell of the regulator comes apart, it being necessary to make the same in two parts, that the internal pieces may be more readily handled and adjusted. This joint to be suitably packed. The holsters L L' are, practically, for the purpose of concentrating the water in the pan A directly beneath the bottom of the milk-pan A when but little milk is in the latter, making a saving of water and insuring less rapid cooling of same, as the depth of the water is greater in proportion to its surface than it would be were the bolsters omitted.

The entire apparatus is to be supported on any suitable foundation, and to be constructed of any suitable materials in any of the known A. f FFIQE.

by means of the screw S and wheel T.) Water is then supplied vto the-tankA through thebevel-inlet B, the water passing under the' pau A and rising up and around it till it reaches the top of the gate in the regulator E, over which it flows, passing down and outzat the bottom of the regulator. -Should it be' found that the gate P be set too high or too lowthe; same is regulated by thewheel `T at the topof the regulator. The water ows-through an aperture in the side of the tank A into the.-

regulator E, said aperture being,k in length, vertically, from bottom of pan A to .a line` `near its top. When the nii-lk is -sutlciently cooled the Water is-drawn from the tankA through the pipes J J and faucetK, or by low-` ering the gate in the regulator E,.the milk passing out of the pan A' through the pipe Gr by drawing the plug I.

What I claim as my invention is l. In combination With the pan A and tank A, the'double-shouldered pipe G, being a tixture in the bottom of Water-tank A, reaching close to bottom ot" milk-pan A', and having a rubber packing or gasket at its upper end, all

rl being arranged and to operate substantially in the manner set forth. f

2. In combination with the milk-pan A and 5 the double-shouldered yfixed pipe G, the short tube V, being a fixture in the bottom of the milk-pan A', having one side of its lower end truncated, substantially as andl'for the purpose set forth.

3. In combination with the Water-pan A and the milk-pan A the Water-regulator E, composed of a suitable shell of one or more pieces, havin-g at its upper part the inlet O, over "which inlet slides an adjustable gate, P, properly packed, kept in position laterally by means VAof guidesv R R, controlled in height by screw S and Wheel T, and lnade water-tight by screwpressurebar U andlwhe'el F, the lower part of the regulator having an outlet to which may be connected a` pipe or drain, operating in the manner. andfor the purposes as set forth.
